Verifying email addresses before you hit send can ensure your messages land in the right inboxes, enhancing deliverability and engagement rates. If you want to understand email validation to boost your marketing and drive maximum conversions, continue reading to learn more!

In this blog, we'll explore how to validate email addresses using email verifiers and checkers and explain how to choose an email checker tool for your business. 

What is Email Validation?

Email validation is a crucial process that scans the email addresses in your contact list and ensures their accuracy to enhance the deliverability of your email campaigns. It involves a series of systematic checks designed to verify whether an email address is correctly formatted, exists on the specified domain, and can successfully receive emails, all by using an email checker.

This process is essential for maintaining a clean email list, reducing bounce rates, and improving overall email campaign effectiveness by ensuring you don’t email spam traps or temporary email IDs, thereby increasing your sender’s reputation. 

If your sender’s score or reputation is low, then the recipient’s Internet Service Providers (ISPs) will flag all the communication from you as spam and add you to a block list. It is a common issue that most businesses face when they have to send bulk emails daily. Hence, improving your sender’s reputation is of utmost importance. 

Understand the Email Validation Process

An email verifier uses a collection of complex checks to ensure that all the email addresses in your contact list are active and can receive emails. An email checker uses the following validation process:

1. Syntax Check

The first step in the email validation process is to verify that the email address is correctly formatted according to standard email syntax rules. This includes:

• Ensuring the presence of an "@" symbol.
• Checking for a valid domain (e.g., .com, .net, .org).
• Validating that the local part (before the @) and the domain part (after the @) contain only permissible characters.

2. Domain Check

After confirming the syntax, the next step is to ensure that the domain exists and is operational. The domain email address functions like your virtual address, ensuring all the emails are routed to your address. This involves:

• Email verifiers check the DNS (Domain Name System) records to verify the existence of the domain.
• The checkers ensure that the domain has a valid MX (Mail Exchange) record, which indicates that it can receive emails.
• Some email providers also offer a domain verification process with DKIM (Domain Keys Identified Mail), and the email verifier checks this, too. The DKIM is an authentication protocol that reduces the chances of email spoofing and ensures that the email indeed belongs to the domain it is sent from.

‍

3. Mail Server Validation 

This step involves communicating with the mail server to confirm that the specific email address exists. It includes:

• Using the SMTP (Simple Mail Transfer Protocol), the outbound email protocol, to simulate sending an email to the address.
• An email checker observes the server’s response to determine if the address is deliverable or will result in a hard bounce (your email will never reach a particular recipient). This is in contrast to a soft bounce, which is a temporary deliverability issue where emails will eventually be delivered. When there is a hard bounce, it means that delivery to this address results in a permanent failure. 

4. Role-Based Account Detection 

Email checker tools can identify whether an email address is role-based (e.g., info@domain.com, support@domain.com) rather than associated with a specific individual. Role-based emails are often less valuable for marketing purposes and may require different handling.

5. Spam Trap and Blacklist Check 

Some email addresses are set up as spam traps to catch spammers. The email checker can evaluate the email address against known spam trap databases and blacklists to ensure that the address does not pose a risk to your sender's reputation.

6. Disposable Email Detection 

Disposable email addresses are temporary and often used for short-term purposes, such as 10-Minute Mail or 5-Minute Mail. Email validation tools can identify these addresses to help you avoid including them in your email list and streamline your marketing campaigns.

Benefits of Email Validation

There are several benefits associated with the email validation process, including enhancing your sender’s reputation to ensure you can seamlessly use email blast tools to send mass emails. Let’s have a look at each of these advantages.

1. Improved Deliverability 

Email verifier ensures that your messages reach real and active inboxes, reducing bounce rates and enhancing deliverability.

2. Enhanced Sender Reputation 

High bounce rates and sending emails to invalid addresses can damage your sender's reputation. Email validation helps maintain a good reputation with ISPs (Internet Service Providers), further contributing to efficient email delivery. 

3. Cost Efficiency 

By removing invalid or low-quality addresses from your list, you save on email marketing costs. As most email service providers charge based on the number of emails sent or the size of your list, by only keeping active addresses, you can significantly reduce cost and reinvest it elsewhere. 

4. Better Engagement 

A clean email list means your messages are more likely to reach engaged and interested recipients. This leads to higher open rates, click-through rates, and overall engagement, thus making your marketing campaigns more successful. 

5. Accurate Analytics 

With a validated email list, your email marketing analytics become more reliable, giving you a clearer picture of your campaign performance and audience behavior. An email checker provides you with data that enables you to understand your resource consumption and how you can improve and streamline them.
